A company spokesperson told NBC 7 on Saturday that it is not yet known how long this all-day breakfast experiment will run. If it’s successful, he said, the company may consider prolonging the test in San Diego.

He said managers will speak with customers about their experience with the menu to gauge the response.

The spokesperson said this test run is something customers have been wanting for a long time.

“Our customers have been asking for breakfast all day for quite some time and today, in San Diego, we’re making that happen,” he added.

The San Diego Business Journal reported earlier this week that the company has recently been “tweaking its menu in response to sagging sales and increasing competition from other chains now offering breakfast, most recently including Taco Bell.”
